Instructables


This Instructable shows you how to build a simple, inexpensive breadboard for robotics experiments. It is a companion to Cheap, Easy Robotics for the Non-Programmer. Here we'll learn how to build a Babuino robot to use for experiments with the Babuino/Blocos software environment. Using a breadboard like this makes it easy to experiment with robotic circuits. Since no soldering is required, it's also very easy to make changes to your circuits. (Note that some soldering is required to build the breadboard, but it's pretty minimal.)

This website (featured in the last Instructable) provides a great design for a simple robot. That platform is both simple and elegant, but has two short-comings for an individual wishing to experiment with robotics. The first is that the platform really wants to be built for a class. That is, the tools and setup to build it may be beyond an individual who does not have a fairly complete shop (like a band saw or jig saw) and the materials become economical when purchased in quantity. The other short-coming is that the platform is fairly specific once the Radio Shack prototype board is built. Sensors, motors, etc. are soldered in place, so making changes is difficult.

There are many other examples of simple robots and Arduino clones on the Internet. Pointers to some of these were given in the last Instructable, and lots more can be found with Google. So why am I reinventing the wheel? Simply to bring together in one place all the pieces you need to build a robot breadboard, complete with motors and motor controls, at minimal cost and assembly effort. Add the environment from the last Instructable and have a blast with robotics for a tiny investment.

First, I'll show you how to build the mechanical platform, then we'll add the Babuino controller. Two alternative Babuino incarnations will be presented. The first will be an actual Arduino clone, using the same processor used on Arduino and having exactly the same hardware resources. The second is a simpler to use version with a built-in USB interface and additional hardware resources. Both will work great, pick your favorite.

Important Note: When I use the name “Arduino” I mean not just the (not quite copyrighted) Arduino itself, but also the many public domain versions collectively known as “Freeduino”. In some cases I use the term “Ard/Free-duino”, but the terms should be considered interchangeable for the purposes of this Instructible.

I’m working on a project which is about making a rescue
robot . I have struggling with it for 4 months and now all the mechanical works
had been done . but I’m facing difficulty in make the robot to work with rf
module can u plzz help me…

I want make transmitter and receiver that can control the
motion…I mean that receiver should have control 8 dc gear motor and each dc
motor should have a forward and backward botton to control the motion ……can u
kindly help me with this project ….if u can make the circuit board diagram for
the PCB ….or any other suggestion plz reply……mail me at “sunny1995gagan@gmail.com”

Hey shall we use any other motor which drives the robot fast( i mean servo motor) ????????????????PLZ HELP ME. IF SO WAT ARE THE CHANGES!

A modified servo motor (as described in the links) works just fine. After modification, it is basically just a DC motor and is controller the same way. Servo motor control from the Babuino is planned, but not implemented yet.

You could also use a DC gear motor with a different gear ratio to give higher speeds.
Mr.Doctek plz help in motors!!!!!!!!

could i use solar panels instead of batteries
doctek (author)  Prince5653 years ago
Should work fine. The important thing is to be sure the processor and the 5V side of the HBridge never see any voltage higher than 5V. Solar panels put out a voltage that is actually pretty variable. Using some sort of voltage regulation / charge controlling circuit would be important.

The other option would be to simply use the solar panels to charge the batteries you use. ;)}
which batterie pack should i change to the solar panels the two pack AA or the 4 pack AA or should i just use one 6v solar panel and no batteries
doctek (author)  Prince5653 years ago
Important: I am not an expert on solar power! So anything I suggest is along the lines of thoughts and questions to investigate, not design info.

First, all 6 batteries are used to power the robot, so it would seem that the solar panel should charge or replace them all,depending on the route you're planning.

I have two main concerns. First is that the 5 Volt power supply must never see over 5 volts, as I've mentioned before.

Second is whether or not a small panel can provide the power to run the motors. I don't know what size panel would be required.

Good luck! Maybe it's another Instructable.
